UNITED STATES GEORGE C. JORDAN, OF EAU CLAIRE, WISCONSIN.

VENTILAT OR.

Application filed May 4, 1921.

T 0 all whom it may concern:

Be it known that GEORGE C. JORDAN, a citizen of the United States of America, residing at Eau Claire, in the county of Eau Claire and State of lVisconsin, has invented new and useful Improvements in Ventilators, of which the following is a specifica tion.

The object of the invention is to provide a ventilator for draught flues, smoke outlets such as chimneys and stacks and the like, whereby not only is a down or counter draught prevented but the movement of the outside air adjacent to the device serves to induce a suction and hence increase the up-draught efficiency, and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawing, wherein:

Figure 1 is a front elevation, of the apparatus viewing the same in a direction counter to that of the movement of the air by which the revoluble member of the device is positioned.

Figure 2 is a plan view of the same on a reduced scale.

Figure 3 is a vertical sectional view on the plane indicated by the line 33 of Figure 2.

Figures 4 and 5 are detail views of hear ing spiders for the spindle of the revoluble member.

Figure 6 is a sectional view of the revoluble deflector or cowl separated from the flue.

The device is designed for use in connection with a chimney, stack or other similar smoke air or gas outlet which may be represented for the purposes of disclosure by the flue section 10 which is open at its upper end and is fitted with a protective deflector or cowl preferably of cylindrical form as shown at 1'1 and of a diameter exceeding that of the portion of the flue surrounded thereby, said deflecting cylinder being of a depth or vertical extent which adapts it to occupy a zone reaching from a plane below the upper end of the flue to a plane considerably above said flue to permit of enclosing within the deflector a trunco-conical cap 12 supported by standards 13 to permit of free exhaust from the upper end of the flue in all directions.

The deflector is open at its upper end as at its lower end and centrally is provided with a conical hood 14: of an area at its base approximately co-extensive with the flue and Serial No. 466,655.

hence of somewhat greater area than the upper portion of the cap 12 which latter, however, extends at its base beyond the area of the fine to provide a downwardly flared shield 15, overhanging the lateral outlet from the flue and corresponding with a downwardly flared, trunco-conical shield 16 which is carried by the flue at its upper end and hence is disposed below said lateral outlet thereof.

For a distance approximately one-half of r;

the circumference of the deflector the latter is provided in the plane of the space between the shields 15 and 16 with a vent opening 17 having upper and lower downwardly inclined guard flanges 18 and 19 and side flanges 20, said deflector being mounted for a revoluble movement and to this end having a central spindle 21 extending axially through the conical hood l4 and carrying a vane 22 designed to be acted upon by the movement of the outside air to position the vent opening 17 of the deflector at the lee ward side of the flue.

In order that the movement of the defiector may be comparatively sensitive to permit of prompt adjusting thereof to correspond with the direction of movement of the air, the spindle is preferably provided with anti-friction bearings on the flue as for mple by providing it with a bearing disk 23 arranged in operative relation with a bearing spider 24 supported by radial braces 25 extending inwardly from the uprights 13 and having in common with said disk a ball race 26 for the reception of anti-friction 555 balls or rollers 27. A corresponding bearing may be provided at the lower end of the spindle but in the construction illustrated, and designed to represent a ventilator of small or moderate dimensions the lower end 1 open top and bottom of the deflector cylinder air may enter the same at the wind ward side of the flue but in that event its passage diametrically across the upper end of the flue through the outlet space provided between the planes of the shields 15 and 16 to the vent opening 17 will tend to induce suction in the flue which will increase the up-draught in the latter and hence the ventilating eflect oi the apparatus, and obviously the movement of the outside air around the deflector will tend to cause a similar suction at the vent opening 17 which also will enhance the efliciency of the device. Down-draughts or currents tending to act in a direction counter to the discharge from the flue will be prevented not only by the position of the deflector cylinder but also by the t'runco-conical shields and more especially the upper of the two shields which is located immediately beneath the conical hood 14 and extends peripherally beyond the circumference of the hood as hereinbefore explained.

The conical hood 14 is carried by the spindle 21 through the agency of a spider having the arms 31 and the cylindrical deflector is in turn supported by the hood through the agency of radial arms 32 while a lateral opening 83 in the hood at the side corresponding with and over the opening 17 in the deflector is provided with a canopy 34 whereby while an outlet of air or products of combustion is thereby afforded the entrance of rain through the opening 33 is prevented.

lVhat is claimed is:

1. A ventilator having, in combination with an upright flue section, a revoluble cylindrical deflector of a diameter exceeding and surrounding the outlet of the flue section in spaced relation therewith and provided with a side outlet opening protected by upper and lower downwardly inclined guard flanges, said deflector being carried by an upright spindle arranged in axial relation with the flue section and mounted thereon, and a vane carried by said spindle and located above the plane of the deflector for positioning the latter with its opening at the leeward side of the flue section, a conical dome being attached to and carried by the spindle above and in spaced relation with the outlet end of the flue section and serving as a support for said deflector.

2. A ventilator having, in combination with an upright flue section, a revoluble cylindrical deflector of a diameter exceeding and surrounding the outlet of the flue section in spaced relation therewith and provided with a side outlet opening protected by upper and lower downwardly inclined guard flanges, said deflector being carried by an upright spindle arranged in axial relation with the flue section and mounted thereon, and a vane carried by said spindle and located above the plane of the deflector for positioning the latter with its opening at the leeward side of the flue section, a conical hood being attached to and carried by the spindle above and in spaced relation with the outlet end of the flue section and serving as a support for said deflector, the hood being provided with a lateral opening at the side corresponding with the opening in the deflector and being provided with a protecting canopy.

3. A ventilator having, in combination with an upright flue section, a revoluble cylindrical deflector of a diameter exceeding and surrounding the outlet of the flue section in spaced relation therewith and provided with a side outlet opening protected by upper and lower downwardly inclined gua'rd flanges, said deflector being carried by an upright spindle arranged in axial relation with the flue section and mounted thereon, and a vane carried by said spindle and located above the plane of the deflect-or for positioning the latter with its opening at the leeward side of the flue section, a conical dome being attached to and carried by the spindle above and in spaced relation with the outlet end of the flue section, and downwardly flared upper and lower trunco-conical shields disposed in spaced relation respectively above and in the plane of the outlet end of the flue section and of larger diameter at the bases than said dome.

4. A ventilator having, in combination with an upright flue section, a revoluble cylindrical deflector of a diameter exceeding and surrounding the outlet of the flue section in spaced relation therewith and provided with a side outlet opening protected by upper and lower downwardly inclined guard flanges, said deflector being carried by an upright spindle arranged in axial relation with the flue section and mounted thereon, and a vane carried by said spindle and located above the plane of the deflector for positioning the latter with its opening at the leeward side of the flue section with the upper and lower edges of the ture.
